Battery sulfation low current repair
Luckily, sulfation can be reversed and prevented. The lead sulfate that has hardened and crystallized, which can't be removed by charging, can be removed by another process, called desulfation. This is the most important aspect of battery reconditioning. Applying a very high voltage to the battery plates. As we mentioned earlier, discharging a battery means sulfation will develop. Fact. There's nothing you can do about it. The more discharge, the more lead sulfate develops on the battery. Sulfation is not the only issue that can afflict batteries. There is also acid stratification, which can also be called acid layering. A well-rounded and full battery reconditioning process will. Around 50% of all breakdowns are due to battery failure.

Why capacitors are protected against low voltage
This overcurrent relay detects an asymmetry in the capacitor bankcaused by blown internal fuses, short-circuits across bushings, or between capacitor units and the racks in which they are mounted. Each capacitor unit consist of a number of elements protected by internal fuses. Faulty elements in a capacitor unit are. Capacitors of today have very small losses and are therefore not subject to overload due to heating caused by overcurrent in the circuit. The capacitor. In addition to the relay functions described above the capacitor banks needs to be protected against short circuits and earth faults. This is done with an ordinary two- or three-phase short.
